Homework Help: Angular Velocity of gears

  1. Nov 29, 2006 #1
    1. The problem statement, all variables and given/known data
    Gears A and B are connected by arm AB. The angular velocity at A is 60 rev. per minuter (clockwise), find the angular velocity at B if
    a) wAB = 40 rpm (counterclockwise)
    b) wAB = 40 rpm (clockwise)

    2. Relevant equations
    w=dTheta / dt
    w = v/r

    3. The attempt at a solution

    solved for linear velocity for A (=480) do not know what to do next

    Is there a figure that goes with this question? What does it mean to connect two gear sprockets with an arm? Is it a toothed arm and A and B have diffeferent radii?
